You can also standardize semantics (with our without a concrete
syntax) without talking about behavior, as is done for knowledge
representation languages like RDF.  Informally, the semantics allow
each party to make factual statements which others are free to act on
as they like.  This allows a kind of shared knowledge to emerge --
which I think counts as "interoperation" -- without any comment about
behavior.  (If we want to talk about which knowledge is really *true*
we may need to talk about the behavior of only stating true things,
but that's not part of the RDF specs.)
